I was dead set on using Shiva X-2s in my setup. However the June ETA date came and went, and now Kevin tells me that his manufacturer is basically non-functional and no eta on when/if new Shivas will be made. So I need to pick between my alternatives (unless you are lookin to sell a 12" Shiva in good condition :p).

Application
Enclosure: 1.5 cu ft sealed fiberglass box (fitted for trunk side, stealth-install style). cutout for 12"
Power: JL Audio HD 750/1
Focus: Sound Quality* >>>> SPL
Uses: Bass and beat heavy music - metal, trance, techo, raggae, hip hop, rap, dubstep, grime and any other name you've got for something that gets low and grimy and fast. BUT ALSO, a lot of prog rock and 'hi-fi' tracks. Think Tool, Pink Floyd, occasional classical music. Needs to handle these and shine doing it.
Front Stage: JL HD 600/4 driving 4x HAT Imagine I61-2 all around. May upgrade to Clarus or L6 setup at some point.

Price difference for the above 3 options is not a consideration.

* What SQ means to me: "low noise floor, inaudible levels of distortion, good tonal accuracy, good dynamics, and good stage/image." (a quote i lifted from another forum that really hit the nail on the head for me). Keeping in mind the application of said sub in terms of music types. Another way I like to define a high-SQ set up is that it has a 'warm' sound... vs harsh. I know that's even worse a term then 'SQ' to begin with, but for anyone who plays bass, its the difference between a Mesa Amp/Cab or possibly a high-end Peavy, vs something like Hartke or even SWG. Played with a Warwick Thumb bass. Hope that makes sense...

Wow, this is strangely similar to my dilemma with a 10" sub. FYI, my 10" IDQ doesn't have enough output/low end for me. However, the box is a bit on the small side (but not that much, probably 0.65ft3, so within spec). I would go IDmax if you have the space. I also have been considering a TC sounds epic. It has like 20+ mm excursion, so it's got that going for it.

Why not an Image Dynamics IDMax 12"?

Here would be a link to one of them:
WoofersEtc.com - IDMAX12-D4 - Image Dynamics 12" 1800 Watt Subwoofer

OK, so read some reviews on the IDMAX and man that DOES sound very appealing. A little thick on the low end (perfect for my application), recommended sealed enclosure is exactly at 1.5 (so I'll be a little smaller after displacement, but was planning on stuffing with Polyfill anyway so not a concern). And Sonix Electronix has the D4ohm at $339 - very reasonable new. We may have a winner, but going to look some more.

12W6. Ran them for many years, absolutely loved them and they're bulletproof too.

There's also a new AE IB12 for sale on here. The AE IB15 is the absolute best sounding sub I've ever heard. Not sure if you would be willing to go IB or not. They literally give you the best of all worlds. Sooo detailed, tight, quick, but reach incredibly low. As one of my friends said, it sounds like I have a couple high end 10" subs in there on the tight stuff..... Yet they reach REAL low with authority.

Yes, and as you said earlier, only a +2db gain at 20hz, dead even at 30hz, and the IDQ wins above 30hz.

There is an IDMax12 for sale in the classifieds section for $250 shipped, with a brand new recone.
